As the glass caps vary in size, however,to a limited extent, some will fit too loosely into the covers, and willbecome detached too easily. The small sharp ribs to, however, penetratethe metal on forcing the cap into the cover, and will retain their holdof the latter until an effort is made to remove them, when removalbecomes necessary.
